Bridges Claude to netcoredbg via the Debug Adapter Protocol, letting the agent pause your running .NET app, inspect variables, set breakpoints, and mutate state mid-execution. Ships with netcoredbg binaries for Linux, macOS, and Windows, so no separate debugger install. You get 27 tools ranging from raw DAP primitives (attach, set breakpoint, evaluate expression) to agent-friendly composites like exception_autopsy, hang_analyze, and stack_explore that bundle multi-step debugging workflows into single calls. Reach for this when you want Claude to ground its answers in actual runtime values instead of guessing, or when you need to test a fix hypothesis by mutating variables without restarting the process.
